A triggering device for a horn system of a motor vehicle is integrated in a steering wheel () of the motor vehicle. In order to prevent a relative movement of components associated with the steering wheel in relation to each other, but still enable a secure and reliable actuation of the triggering device of the horn system while at the same time allowing an optically compact and appealing design of the steering wheel (), the invention proposes for the triggering device to comprise a first triggering unit (), with which a parameter inherent in intended activation of the horn is detected. When such a parameter is detected, a first triggering signal can be emitted. The invention comprises a second triggering unit (), with which a further parameter inherent in an intended activation of the horn is detected and a second triggering signal can be emitted. By means of the triggering device (), the horn system of the motor vehicle can be put into operation when the first triggering signal is emitted by the first triggering unit () and the second triggering signal is emitted by the second triggering unit ().

Triggering device for a horn system of a motor vehicle

A housing for an airbag module for arranging on the steering wheel of a motor vehicle comprises a hinge mechanism for pivotably fixing the housing to a steering wheel and at least one fixing mechanism for additionally mounting the housing on the steering wheel in a floating manner. The hinge mechanism and the fixing mechanism are arranged at a distance from each other. The inventive housing also comprises a contact mechanism for triggering a vehicle horn. The contact mechanism is arranged at a distance from the hinge mechanism, and the housing mounted in a floating manner can be pivoted about the hinge mechanism in order to trigger the vehicle horn by applied pressure.

Housing for an airbag module

The invention relates to a steering wheel comprising a steering wheel body ( ), an airbag unit ( ), a detent connection for fixing the airbag unit to the steering wheel body, a contact device having a first and a second contact ( ) that are short-circuited for triggering an electric function element, especially an electric horn ( ), when the airbag unit is moved in a direction toward the steering wheel body by a pressure exerted on said airbag unit. According to the invention, one of the detent elements of the detent device is, at least in part, electrically conductive and simultaneously forms the first contact ( ) of the contact device. When an airbag is fastened according to the floating horn principle, the number of required parts is further reduced and it is possible to easily and securely fix the airbag unit to the steering wheel without the use of tools.
